I can try to write some stuff up, it’s not super complex. Core requirement for my setup is Docker + a domain. I recommend Linux host but you can make Docker Desktop work.

Let me write some stuff down this week.

I’m running a Matrix server with a FB Messenger bridge via mautrix-meta and that makes it a clear winner. Half my group chats have migrated entirely since I’ve set my close friends up with accounts in my server and they also use the bridge. The fact that people can slowly migrate chats without losing messages or groups is killer for adoption imo.
